Disease relevance of Ndst1

  • The NDST-1 null mice developed respiratory distress and atelectasis that subsequently caused neonatal death [1].

High impact information on Ndst1

  • We show that properly synthesized heparan sulfate is required for the normal development of the brain and face, and that Ndst1 is a modifier of heparan sulfate-dependent growth factor/morphogen signalling in those tissues [2].
  • Mutant mice bearing a targeted disruption of the heparan sulfate (HS) modifying enzyme GlcNAc N-deacetylase/N-sulfotransferase 1 (Ndst1) exhibit severe developmental defects of the forebrain and forebrain-derived structures, including cerebral hypoplasia, lack of olfactory bulbs, eye defects and axon guidance errors [2].
  • Heparan sulfate synthesized by mouse embryonic stem cells deficient in NDST1 and NDST2 is 6-O-sulfated but contains no N-sulfate groups [3].
  • All these modifications are believed to depend on initial glucosamine N-sulfation carried out by the enzyme glucosaminyl N-deacetylase/N-sulfotransferase (NDST) [3].
  • In vitro translation of a reporter gene located downstream of the UTRs demonstrated the presence of internal ribosome entry sites, providing an additional, cap-independent step in fine-tuning NDST expression [4].

Anatomical context of Ndst1


Associations of Ndst1 with chemical compounds

  • Cerebral hypoplasia and craniofacial defects in mice lacking heparan sulfate Ndst1 gene function [2].
  • Glucosaminyl N-deacetylase/N-sulfotransferase (NDST) catalyzes the first modifying step in the biosynthesis of the polysaccharide [6].
  • The initial modification of the precursor polysaccharide, N-deacetylation followed by N-sulfation of selected N-acetyl-D-glucosamine residues, is catalyzed by the enzyme glucosaminyl N-deacetylase/N-sulfotransferase (NDST) [5].
